Apple Health Ingester

Simple HTTP server written in Go that ingests data from Health Auto Export into multiple configurable storage backends.

Why?

The Health Auto Export app (https://www.healthexportapp.com) allows you to easily export Apple Health data from your iOS device into a portable format, and currently supports exporting to various sinks such as Google Drive, Dropbox and Home Assistant.

As such, this simple HTTP server will receive requests from the Health Auto Export app via the REST API export method, which allows the flexibility to export data into one or more configured backends.

Features

Supports multiple backends for writing metrics.
- Local File: Writes the ingested payloads into the local filesystem as JSON.
- InfluxDB: Writes the ingested metrics and workout data to InfluxDB (or any other databases that support the protocol such as VictoriaMetrics).
Supports ingestion of data separately from multiple iOS devices.
Optional Bearer authentication to protect publicly exposed endpoints.

Setup Instructions

Health Auto Export Setup

You will first have to download the Health Auto Export iOS app on your iOS device.

NOTE: You will need to purchase a Premium subscription, or use the free trial in order to enable Automations.

In the app, create a new Automation:

Under Automation Type, select REST API.
Enter the URL to your server (see below for instructions on how to run the server).
- The URL should look like http://your.domain/api/healthautoexport/v1/influxdb/ingest
- Optional: To identify the source of data (i.e. the person's whose health is being tracked), add ?target=NAME to the end of the URL, where NAME is a friendly name such as John. This will enable target name tracking in the ingester.
Under Export format, select JSON.
You can optionally choose which Health Metrics and/or Workouts to send.
Under Manual Sync, you can select a time range, and click "Export" to test if it is working.

For more detailed instructions, refer to the official site.

Global Configuration

`http.listenAddr`

Address to listen on, in IP:port format. Defaults to :8080.

`http.authToken`

Optional authorization token that will be used to authenticate incoming requests. The header name should be Authorization, and the header value should be Bearer <TOKEN>.

TLS Configuration

To enable TLS, the following flags must be provided:

http.enableTLS: Starts a TLS/HTTPS server instead of HTTP.
http.keyFile: TLS private key file.
http.certFile: TLS certificate file.

`log`

Specify the log level. The following log levels are supported, and in order of verbosity from lowest to highest:

panic
fatal
error
warn/warning
info (default)
debug
trace

Supported Backends

Each backend must be enabled explicitly. By default, no backends are enabled by default.

Additionally, each backend currently has a fixed URL that must be used when configuring the automation in Health Auto Export.

LocalFile

URL: /api/healthautoexport/v1/localfile/ingest

Writes the ingested payloads into the local filesystem as JSON. Mainly intended to be used for debugging purposes, but the logic could be easily extended for file backups on a remote file store (e.g. S3, Dropbox, etc).

Configuration

This backend is disabled by default. You can enable it by specifying --backend.localfile.

You must also configure additional fields for the backend to work. Example configuration:

$ ingester \
  --backend.localfile \
  --localfile.metricsPath=/data/health-export-metrics

NOTE: Workout data is currently not yet supported for this storage backend.

Example Output

This will produce a directory with each metric stored as a separate file as follows:

$ ls -la /data/health-export-metrics
total 2604
drwxr-xr-x 96 irvin   3072 Dec 25 00:15  .
drwxr-xr-x  3 irvin     96 Dec 25 00:11  ..
-rw-r--r--  1 irvin 418389 Dec 25 00:19  active_energy_kJ.json
-rw-r--r--  1 irvin  30279 Dec 25 00:19  apple_exercise_time_min.json
-rw-r--r--  1 irvin   4755 Dec 25 00:19  apple_stand_hour_count.json
-rw-r--r--  1 irvin 124346 Dec 25 00:19  apple_stand_time_min.json
-rw-r--r--  1 irvin     72 Dec 25 00:19  basal_body_temperature_degC.json
-rw-r--r--  1 irvin 851170 Dec 25 00:19  basal_energy_burned_kJ.json
...

If target name is specified during export, then the filename will be prefixed with the target name.

InfluxDB

URL: /api/healthautoexport/v1/influxdb/ingest

Writes the ingested metrics and workout data into a configured InfluxDB backend.

Configuration

This backend is disabled by default. You can enable it by specifying --backend.influxdb.

You must also configure additional fields for the backend to work. Example configuration:

$ ingester \
  --backend.influxdb \
  --influxdb.serverURL=http://localhost:8086 \
  --influxdb.authToken=INFLUX_API_TOKEN \
  --influxdb.orgName=my-org \
  --influxdb.metricsBucketName=apple_health_metrics \
  --influxdb.workoutsBucketName=apple_health_workouts

Metrics Data Format

All metrics will be stored in the bucket named by --influxdb.metricsBucketName using the following format:

Measurement:
- Metric name (e.g. active_energy) + Unit (e.g. kJ)
- Example: active_energy_kJ
Fields:
- Most metrics will use qty for field name.
- Some metrics which have multiple fields will use their corresponding field name. For example, sleep_analysis_hr uses the following field names:
  - inBed
  - inBedStart
  - inBedEnd
  - inBedSource
  - The rest of the fields can be found here: https://github.com/Lybron/health-auto-export/wiki/API-Export---JSON-Format
Tags:
- target_name: Optional, set by ?target=TARGET_NAME query string from HTTP request.
- Additional tags can be set by --influxdb.staticTags.

Workouts Data Format

Workout data will be stored in the bucket named by --influxdb.workoutsBucketName. Workout data is slightly more complicated than metrics. You can read more about the workout data format here: https://github.com/Lybron/health-auto-export/wiki/API-Export---JSON-Format#workouts

There are two kinds of data:

Workout summary data: Contains aggregate statistics about each workout (i.e. one point per workout)
- Measurement: workout
- Fields:
  - Example: activeEnergy_kJ
- Timestamp: Uses the workout's start time
During-workout time-series data: Contains per-minute granularity time-series data
- Measurement: Currently, only the following measurements are supported for this type of data:
  - heart_rate_data_bpm
    - Fields: qty
  - heart_rate_recovery_bpm
    - Fields: qty
  - route
    - Fields: lat, lon, altitude
- Timestamp: Corresponds to the date/timestamp field

All workout data have the following tags:

Tags:
- target_name: Optional, set by ?target=TARGET_NAME query string from HTTP request.
- workout_name: Name of the workout.
  - Example Walking
- Additional tags can be set by --influxdb.staticTags.
